This present work investigates a possible configuration of tubes with cylindrical embedded fins in phase change material for the purpose of latent heat energy storage.Such systems are difficult to analyze theoretically due to the non-linearity of the moving solid liquid interface. In this paper finite volume model is developed to simulate the freezing of phase change material around the outer surface of the circular cylinder finned tube.This simulations predicts the fraction of melted phase change material (PCM),and the shape of the liquid solid interface as function of time.The results are compared in dimensionless from with available references and show fairly good agreement.The model has demonstrated that a shorter discharge time and higher amount of energy can be achieved by increasing the fin diameter and thickness,the number of fins,the temperature deference between phase change material and tube wall .
